Compound fat liquoring agent

Abstract

The invention discloses a compound fat liquoring agent which comprises the following components in parts by mass: 20-28 parts of polyethyleneglycol, 30-35 parts of mineral oil, 25-30 parts of animal oil, 30-35 parts of emulsifier and 1-5 parts of mold preventive. According to the invention, the fat liquoring agent is prepared from polyethyleneglycol, mineral oil and animal oil, so that the fat liquoring agent can be favorably combined with leather fibers, and leather can be endued with fine softness, smoothness and fullness, thereby ensuring that the leather feels oily and mild and is fast to light.

Description

technical field [0001] The invention belongs to the technical field of leather auxiliary agents, and in particular relates to a composite fatliquoring agent. Background technique [0002] Fatliquor is an important leather chemical in leather processing. Fatliquoring in the leather processing process is to treat the leather with a fatliquoring agent under certain technological conditions, so that the leather can absorb a certain amount of oil and endow the leather with certain physical, mechanical and usable properties. The fatliquoring agent can make each fiber inside the leather wrapped by lubricating oil or a large number of oily molecules on the surface of the fiber through chemical and physical actions, balance the surface energy of the leather fiber, change the original high-energy surface into a low-energy surface, and increase The mutual mobility between the fibers prevents the leather from hardening and cracking, and makes the leather have good physical and mechanic...

AI Technical Summary

Problems solved by technology

But at present, there are few types of leather fatliquor, single performance, and most of them have poor combination with leather fibers, which cannot meet the needs of leather production.
